MOTOR PROTECTION FUNCTION
If the rotation of the turntable has not reached constant speed after 30 sec, the motor will stop and the power indicator
#4 will flash.
If the motor stops and the power indicator flashes, press any speed button to restart.
STANDBY
This device has an automatic standby mode which is activated after 20 minutes of non-use. At this time, the power
indicator light will turn from blue to red.
In standby mode, the power consumption of the turntable is reduced to less than 0.3 W to avoid unnecessary power
consumption.
AUTO STOP
Auto stop, also known as auto shut off, stops the platter from spinning approximately 20 seconds after it has finished
playing the record. The arm will not automatically raise.
Pushing any speed button will restart the motor.
SETUP and ASSEMBLY
Some assembly is required before you can begin to use your new unit.
Please follow the assembly instruction below before attempting to use your new turntable.
Do not connect your turntable to a power outlet with the AC adaptor until you have finished the assembly.
Do not remove the twist tie securing the tonearm until assembly is completed.
PRECAUTIONS ON PLACEMENT:
1. Do not place the unit in a location where it will be exposed to direct sunlight or near any type of heating appliance.
2. Do not place the unit in a location where there is high humidity or a lot of dust.
3. Cartridge may pick up slight sound pressure or vibrations from nearby speakers. For best results, do not install this
unit too close to loudspeakers.
4. Install this unit on a horizontal surface that is stable and vibration free.
5. The feet have been specially designed to isolate the unit from excess vibration. The feet are adjustable and should
be used to level the turntable.
NOTE:

SETUP and ASSEMBLY

ASSEMBLY
1. Remove the main unit with the packing material from the box.
2. Mount the turntable platter onto the center spindle.
3. Install the rubber mat on the platter.
4. Installation of cartridge: (if required)
When installing a new cartridge, refer to its’ spec. sheet in order to apply correct tracking force.
During installation, attach the stylus protector to guard the stylus tip from damage.
Connect the lead wires to the cartridge terminals. The terminals of most cartridges are color-coded.
Connect each lead wire to the terminal of the same color.
White (L+) Left channel+
Blue (L-) Left channel-
Red (R+) Right channel+
Green (R-) Right channel-
Install the cartridge to the head shell and tighten it with screws provided with the cartridge.
The Stealth turntable comes with an Ortofon 2M Blue cartridge already fitted on the head shell.
5. Insert the head shell firmly into the front end of the tonearm. Turn the lock nut counter- clockwise until tightly
attached.
6. Slide counterweight on the tonearm with the numbers facing towards you. Twist it lightly and it will screw onto the
rear shaft of the tonearm. Advancing the counterweight to the white cross-hatch will give you an effective tracking
force of 1.8g and allow you to skip steps 8-10.
7. An additional counterweight (Sub weight) is supplied for use with a heavier cartridge (see page 9)
8. Adjustment of horizontal “zero” balance and stylus pressure:
(a) Remove the stylus protector from the head shell, do not touch the stylus tip during adjustment.
(b) Set the cueing lever to the lowered position.
(c) Release the tonearm clamp and lift the tonearm from the arm rest to free it.
(d) Supporting the head shell with your left hand or index finger, rotate the counterweight until the tonearm is
approximately balanced horizontally (It may move side to side but should not move up or down).
(e) Refasten the tonearm with the tonearm clamp.
(f) Hold the counterweight stationary with the right hand and rotate the tracking force gauge ring (with
numbers on it) until the number "0" aligns with the center line on the rear shaft of the tonearm. DO NOT
TOUCH THE RING AGAIN.
9. Rotate the counterweight from the back. The tracking force gauge ring will turn with the counterweight. Stop when
you have reached the stylus pressure.
If you are using a cartridge other than the one supplied, please follow the correct tracking force as specified by the
manufacturer’s instructions.
10. Set the anti-skating control knob to the same value as the stylus pressure.
11. The feet can be adjusted by screwing or unscrewing. The table should be leveled before playing.
